Singer 431g question
Found a very nice Singer 431 G on Norwegian website, at a very good price because of a missing foot pedal. I have a few of those. Really elaborate, good work table, but thrashed. Suits me fine to chop it actually, no room for more cabinets. Besides, the machine has a very useful, narrow free arm and I don't know if this could be used in the table.
The sm was just about plug and play. Just a few twists of the hand wheel and it felt nice and loose. Motor running fine, all functions and levers working effortlessly. Haven't actually sewn it yet, because I noticed slack in the ZZ mechanism, I could wiggle the needle bar without resistance.
Opened up up the top again, and found this spring lying loose. Does anybody have a functioning sm in this series, and can show me where the spring goes? Maybe a service manual would show it, but I haven't gotten that far yet.
And then there's the chainstitch. It has been discussed here, but as I only have a vague idea of what it is, and none at all of when it's useful, I haven't really understood it. There was no extra throatplate with the machine. I understand that chances are slim in the US, so I guess German eBay might be a good start for one.
